Hey all, My MacBook recently made a “pop” sound and instantly turned off. A small puff of smoke came out, and a bit of a burning smell. I decided to investigate, and found this chip on the back of the logic board had blown out. Funny thing is, I tried turning the mac back on once right after the incident happened, and it seemed to turn on just fine. Any ideas what this chip does, and if I will need to fully replace my board? Images can be found here: http://imgur.com/a/KPaut

@partidor it is a bit hard to see on your image. It’ll help if you can add an image a bit closer to the actual components. Right now it looks like the component that “popped” is C6432 which is a 100UF 6.3V 20% tantalum capacitor in a CASE-AL1 package. It is part of your audio amp circuit. This answer is of course just to identify the component, not to diagnose what caused it to shorten out.
That is the speaker amplification circuit, and can be repaired. The part that is burned is a C6432. This would be considered an advanced repair and should you choose to have it done professionally you can expect to pay around $200 while a replacement board will run between $349 -$549
Here is a video that will give you an idea of the repair process, while its not the same circuit it is the same process.
